yes, I think we should keep support for old migration, or I think users will complain ;)

Not with unsecure migrations. But yes with secure ones this would be the 
case, they would not crash but simply not work as the tcp tunnel is not 
made. 

We could actually support the old one for some time, even if it is broken 
(not our fault) as we see if we should open a tunnel or not, i.e. if the 
raddr is 
tcp and localhost then open a tcp tunnel like we did, if its tcp and not 
localhost its 
an unsecure and if its unix the do like in this patch. 

comments?
